- Pregnant or breastfeeding women are excluded from this study because inotuzumab ozogamicin may be associated with the potential for teratogenic or abortifacient effects.

About this study
This study has two phases, Phase I and Phase II. The main goal of the Phase I portion of this research study is to see what doses post-transplant inotuzumab ozogamicin can safely be given to subjects without having too many side effects.
The Phase II portion of this study is to see what side effects are seen with medication after transplant.
Inotuzumab ozogamicin is a combination of an antibody and chemotherapy which has been shown to have significant activity against relapsed/refractory acute lymphocytic leukemia (ALL).
Inotuzumab ozogamicin is considered experimental in this study.
Read the detailed description
Study Design This is a Phase I/II study of inotuzumab ozogamicin for the treatment of patients who underwent allogeneic transplantation for ALL and have a high risk of relapse. The Phase I portion of this study will be a 3+3 dose escalation trial. This is followed by a phase 2 cohort at the recommended Phase 2 dose (RP2D). Participants will receive study treatment up to 4 cycles until relapse of disease, unacceptable toxicity, or death, whichever occurs first
Phase I: Inotuzumab Ozogamicin Dosing Escalation Subjects will be assessed for safety and tolerability (including adverse events, serious adverse events, and clinical/laboratory assessments) using a continuous monitoring approach.
Phase II: Inotuzumab Ozogamicin Subjects will be assessed for safety and tolerability (including adverse events, serious adverse events, and clinical/laboratory assessments) using a continuous monitoring approach. In order to be included in the safety profile endpoint review, subjects must have received at least of 1 cycle of treatment.
Primary Objective
Phase I: To define a post hematopoietic stem cell transplantation maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of inotuzumab ozogamicin.
Phase II: To assess the efficacy of inotuzumab ozogamicin as measured by diseasefree survival (DFS) at one year.
Secondary Objective(s)
Phase I:
- To evaluate disease-free survival (DFS), nonrelapse mortality (NRM), relapse, relapse-related mortality and overall survival (OS) at 1 year.
- To determine safety profile of inotuzumab ozogamicin after transplant including the incidence of myeloid toxicity and secondary graft failure and the rate of veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS).
- To determine if inotuzumab ozogamicin at these doses is effective at eradicating minimal residual disease in this cohort of participants
Phase II:
- To assess additional evidence of efficacy and safety as measured by non-relapse mortality (NRM), relapse, relapse-related mortality and overall survival (OS) at 1 year.
- To determine if inotuzumab ozogamicin at these doses is effective at eradicating MRD.
- To confirm the safety profile of inotuzumab ozogamicin therapy after transplant including myeloid toxicity, secondary graft failure, and the rate of VOD/SOS.
- To evaluate the pharmacokinetics of inotuzumab ozogamicin post allogeneic transplant

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study has two phases, Phase I and Phase II. The main goal of the Phase I portion of this research study is to see what doses post-transplant inotuzumab ozogamicin can safely be given to subjects without having too many side effects.
The Phase II portion of this study is to see what side effects are seen with medication after transplant.
Inotuzumab ozogamicin is a combination of an antibody and chemotherapy which has been shown to have significant activity against relapsed/refractory acute lymphocytic leukemia (ALL).
Inotuzumab ozogamicin is considered experimental in this study.
Detailed description
Study Design This is a Phase I/II study of inotuzumab ozogamicin for the treatment of patients who underwent allogeneic transplantation for ALL and have a high risk of relapse. The Phase I portion of this study will be a 3+3 dose escalation trial. This is followed by a phase 2 cohort at the recommended Phase 2 dose (RP2D). Participants will receive study treatment up to 4 cycles until relapse of disease, unacceptable toxicity, or death, whichever occurs first
Phase I: Inotuzumab Ozogamicin Dosing Escalation Subjects will be assessed for safety and tolerability (including adverse events, serious adverse events, and clinical/laboratory assessments) using a continuous monitoring approach.
Phase II: Inotuzumab Ozogamicin Subjects will be assessed for safety and tolerability (including adverse events, serious adverse events, and clinical/laboratory assessments) using a continuous monitoring approach. In order to be included in the safety profile endpoint review, subjects must have received at least of 1 cycle of treatment.
Primary Objective
Phase I: To define a post hematopoietic stem cell transplantation maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of inotuzumab ozogamicin.
Phase II: To assess the efficacy of inotuzumab ozogamicin as measured by diseasefree survival (DFS) at one year.
Secondary Objective(s)
Phase I:
- To evaluate disease-free survival (DFS), nonrelapse mortality (NRM), relapse, relapse-related mortality and overall survival (OS) at 1 year.
- To determine safety profile of inotuzumab ozogamicin after transplant including the incidence of myeloid toxicity and secondary graft failure and the rate of veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS).
- To determine if inotuzumab ozogamicin at these doses is effective at eradicating minimal residual disease in this cohort of participants
Phase II:
- To assess additional evidence of efficacy and safety as measured by non-relapse mortality (NRM), relapse, relapse-related mortality and overall survival (OS) at 1 year.
- To determine if inotuzumab ozogamicin at these doses is effective at eradicating MRD.
- To confirm the safety profile of inotuzumab ozogamicin therapy after transplant including myeloid toxicity, secondary graft failure, and the rate of VOD/SOS.
- To evaluate the pharmacokinetics of inotuzumab ozogamicin post allogeneic transplant

Total range of dose levels for participants is 0.1-0.6mg/m^2. Phase II: Participants will be enrolled until all Phase I participants have been followed and assessed for toxicity for at least 4 weeks after the fourth treatment dose of inotuzumab ozogamicin or 4 weeks after the participant goes off treatment, whichever comes first. Doses to be administered will be determined in the phase I portion of the study. The recommended phase 2 dose is 0.3mg/m2. Repeat cycles every 28 days for up to 4 cycles |

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Inotuzumab Ozogamicin in people with Acute Lymphocytic Leukemia, run by Leland Metheny at 7 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 58 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 10 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
